sars-cov-2 and acetylsalicylic acid (sara)

Conditions: SARS-CoV2 Infection; Covid19

Summary: sars-cov-2 infection in pregnancy is associated with an increased risk of adverse maternal and perinatal outcomes. one explanation is that the infection might increase the existing pregnancy-associated prothrombotic status, leading to a higher risk of placental and vascular complications. administration of low-dose acetylsalicylic acid (ldasa) has shown to improve maternal and perinatal outcomes in women at high-risk of endothelial and placental complications. however, there are no data on the effect of ldasa in preventing complications in sars-cov-2- infected pregnant women. to reduce sars-cov-2- related complications in a highly vulnerable group to the infection, we will carry out this randomized, double-blind, placebo-controlled multicentre trial in 400 sars-cov-2-infected pregnant women. the study main objective is to evaluate the efficacy and safety of ldasa administered up to 36 weeks of gestation in sars-cov-2-infected pregnant women in reducing the incidence of adverse maternal and perinatal outcomes. pregnant women tested positive up to 32 weeks of gestation with a sars-cov-2 rapid antigen or pcr test and agreeing to participate, will be randomised 1:1 to receive daily ldasa (125 mg) or placebo up to 36 weeks of gestation and be followed-up until delivery.
